Wow those colors! O.O And they seem quite big at around 3 months.
Two of mine were born on April 3rd so they're a bit over a month old and barely 1.3 or so cm. They were extremely small when born, maybe because they were the first fry ever born by my female swordie who is also little.
A fry from her latest batch from a week ago is almost as big as his older siblings and is already colored up (red face, black body) but now I have 2 of the same color and a pink one. -.-
I hope they'll get along with the catfish once I put them into the main tank.
